My cart is basically ready to go, but I haven't been able to get my header to work properly. It looks great on Safari, but in firefox it gets all blown out of place, and on a PC in different versions of IE certain colors are missing or different. I have been working on it for two weeks with no luck, so I would like to go back to what I know so I can quickly finish it. I already have the HTML header setup and ready to go, I am just having problems getting it into my cart.

I have tried <?php include 'header.php';?> to pull it in, but when I do my page goes blank from the point after the include. I don't get any errors just a blank page after the include statement loads, before the include everything is there? I'm looking for ideas on how this can be done, or why my page is going blank?
